Latest Patents

Kazumasa Yamazawa holds a patent for a method, system, and computer-readable media for real-time chromakey matting using image statistics. This patent, which is titled "Real-time chromakey matting using image statistics," outlines a three-stage process to identify the chroma key spectrum. The first stage involves semi-automatic calibration of the chroma key parameterization during an off-line training phase. The second stage focuses on real-time classification, where the system estimates the alpha matte on a GPU. Finally, an optional error minimization stage enhances the estimated matte by addressing misclassifications and signal noise. The resulting matte allows for standard alpha blending, effectively merging virtual scenes with live video feeds.
